Tsirbas created the digital model of Deep Space 9 that appeared at the end of DS9: "What You Leave Behind". He commented "I really appreciated working on the last shot of Deep Space Nine. I had a bit of a crusade to prove to the visual effects community that digital animation could look as good as shooting real models. And the space station was always a model. But the very last shot on Deep Space Nine is a pullout from inside the station all the way out, which is impossible to do with the model because if you're in that close the detail just isn't there. So I was tasked to build a digital version of the station and then create this cosmic zoom from inside the station then out through the galaxy until you see a nebula. And that was pretty cool". [1]
